DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

The following description is intended to convey an understanding of the present invention by providing specific embodiments and details. It is understood, however, that the present invention is not limited to these specific embodiments and details, which are exemplary only. It is further understood that one possessing ordinary skill in the art, in light of known systems and methods, would appreciate the use of the invention for its intended purposes and benefits in any number of alternative embodiments, depending upon specific design and other needs.

An embodiment of the present invention is directed to an innovative architecture for location based emergency dialing. The innovative architecture may support various softphone applications. Softphone applications generally include software programs for making telephone calls over the Internet using a general purpose computer rather than a specific hardware component. For example, softphone applications may be installed on a desktop, mobile device or other computer or processing device that allows the user to replace and receive calls without requiring actual telephone equipment. A softphone application may be installed on an Internet-connected device to make and receive phone calls. Current software applications are fairly non-geographic which poses issues with emergency dialing when users travel outside their home regions.

An embodiment of the present invention recognizes that current softphone applications are registered to a home call manager. This one to one mapping means that softphone applications cannot re-register to a different telephone system. Accordingly, softphone applications will connect to the original or home telephone system.

A user may reside in a home region, such as the UK, and use a softphone application to connect with colleagues and clients. While in the UK, the user may interact with an emergency icon, such as by pressing a SOS button. In this scenario, calls may be routed to a UK phone system to contact UK emergency services. According to another scenario, the user may travel to a remote location and work from a US office location. When the user interacts with an emergency icon in the US by pressing a SOS button for example, the call would be routed to the UK phone system where UK emergency services are contacted, instead of local services in the US.

With an embodiment of the present invention, the UK user located in a remote US office location may initiate emergency services that connect with local emergency services. An embodiment of the present invention may verify or confirm the user's current location and then route the call to a local US phone system based on the user's current location. In addition, an embodiment of the present invention may append a suffix location number for a call back feature. With an embodiment of the present invention, a local emergency service may be contacted to provide prompt medical and emergency services and attention. This avoids delays and confusion in having to reroute calls from the user's local phone system (in this example, the UK phone system) to the user's current remote location.

For example, a user may launch a softphone application from a user's physical desktop or terminal. An embodiment of the present invention may identify the user's current location and then provide location emergency services based on the current location. When the user initiates emergency services, an embodiment of the present invention may provide routing on the backend to ensure that the call traverses local services based on the current location.

An embodiment of the present invention may automatically connect the user with a local emergency service. This may involve automatically dialing the local emergency service. According to another embodiment, the present invention may present a local emergency service number to the user. The user may then initiate contact. Other local emergency information may be presented. For example, instructions, messages, notifications and/or other information may be provided to inform and/or assist the user.

An embodiment of the present invention may provide intelligent routing on the backend. For example, if a UK user dials an emergency service while in the US, an embodiment of the present invention may convert the UK user's number on the backend to dial the local emergency service. In this example, based on the user's current location, an embodiment of the present invention may identify a corresponding local security number. Accordingly, when the user initiates an emergency service, the user may see the local emergency number contacted (e.g., county-wide emergency service). In addition, an embodiment of the present invention may identify regional information including a local security number, global security command center information, etc. This information may vary depending on regions, EMEA, APAC, Americas, etc.

A softphone implementation may include a cell phone, mobile device and other equipment. A softphone implementation may also be supported by virtual desktop infrastructure (VDI). VDI may refer to technology that uses virtual machines to provide and manage virtual desktops. For example, VDI may host desktop environments on a centralized server and deploy them to end users on request. An embodiment of the present invention may identify a user's location through a network repository and then using that data, connect to a local emergency services and/or provide information needed to dial the local emergency services.

An embodiment of the present invention may obtain location information from various sources. For example, location information may be provided by switch information associated with the user's equipment. Location information may vary based on current geographic location, compliance considerations, regulations, preferences, privacy settings and/or other information. For example, location information may vary in level of granularity and may include desk location, office level, floor level, zone level, segments, etc. The level of granularity may also vary based on the size of the building, campus, etc.

An embodiment of the present invention may be available as an API so that other users may use the API in other applications, implementations, architectures and systems.

When a UK user is located in the US, the UK user may initiate an emergency services contact. An embodiment of the present invention may perform a lookup using the user's equipment and identify a switch that the user's equipment is connected to. This information may then be used to identify a physical location and a corresponding number that the user may use for local emergency services dialing. The call may then be routed to a local US phone system that may then reach the US emergency services for the particular location the user is at. In this example, a location check may be performed based on the switch identifier where the user is physical situated.

The user may interact with an emergency services icon (e.g., SOS button) that would validate the user's SIM client MAC address against switch information used in the system. A database dip may relate to emergency dialing information and other information which may include seating location, building description, relevant personal emergency information, etc. Other information may relate to what the user needs to dial, where the user's emergency needs to be sent, emergency contact, special emergency instructions/actions, etc.

An embodiment of the present invention may further recognize that different regions may have different requirements. For calls in the US, an embodiment of the present invention may traffic the user's number to provide call-back support. When a UK user is in the US and needs to request emergency services, rather than displaying the UK user's +44 number, an embodiment of the present invention may provide a local number. The local number may be a local building number, a local security team or other designated local number. This requirement may not be needed in other regions.

FIG. 1 is an exemplary process flow, according to an embodiment of the present invention. As shown in FIG. 1, a user may initiate an emergency call. This may involve interacting with a SOS icon, represented by 110. At 112, Thin Client MAC may be validated against a switch identifier. According to an exemplary embodiment, validation may be performed against technology infrastructure and referential data, such as Verum data which represents an authoritative source of data. This data may align to reference data management program's practices and guidelines for technology equipment. Other source data may be applied for validation.

At 114, a database dip may be performed to retrieve call information. This may include a current physical location, office building information, seating area, local number associated with the user, etc. For example, database dip may retrieve information such as GREDL ID, SITE ID, CUCM UCM, Country Code, Metro Area, etc. GREDL (Global Real Estate Data Library) ID may represent data from a repository of building information and related financial data within an entity. For example, GREDL may provide users with detailed information for various locations globally. In the example of a financial institution, this data may include bank locations including ATMs. Information may include building name, address, photos, maps, viewable floor plans, contacts, headcount, lease summaries, financials, cost center allocations, fixed asset values, and scanned legal document images. Each site may have an individual Site ID for identification.

Other information may identify a unified communications manager (e.g., CUCM UCM) which may be associated with an enterprise call control and session management platform that connects users anywhere using a phone or other mobile device.

At 116, a user interface may communicate a message that indicates to the user that an emergency call is about to be initiated. Other messages and instructions may be provided. At 118, a call may be routed via a cloud communication platform. In this example, the platform may be Kandy Platform. Other cloud communications platform may be implemented. A directory URI may represent a uniform resource identifier that may be used to identify a directory number. This may represent an amended form of the user's extension number based on information from the database.

At 122, a call may be routed to a Regional SBC. At 124, SIP locations may route to communication manger, e.g., Cisco Unified Communication Manager (CUCM) Session Manager Edition (SME). At 126, non-SIP locations may route to a local gateway. According to an exemplary illustration, an entity may use a combination of SIP and non-SIP connectivity. SIP is built on the SIP protocol and uses the Internet and data networks to transmit voice calls and is more flexible than some older methods. Other methods may include a Primary Rate Interface (PRI) which may be based on a telecommunications interface standard used on an Integrated Services Digital Network (ISDN) (also known as non-SIP) and generally requires terminating equipment (e.g., gateways) located on site.

At 128, a SOS call may be completed with a correct calling number. At 130, an operator may receive the correct calling number for call back and other features. This may be useful to dispatch medical and other assistance.

While the process of FIG. 1 illustrates certain steps performed in a particular order, it should be understood that the embodiments of the present invention may be practiced by adding one or more steps to the processes, omitting steps within the processes and/or altering the order in which one or more steps are performed.

FIG. 2 is an exemplary architecture diagram, according to an embodiment of the present invention. As shown in FIG. 2, Client 216 may represent a user of a mobile device that implements a soft phone application. For example, Client 216 may represent an employee of a company. An exemplary user device is represented by 214, which communicates network information 212 using a network switch 210 and/or other network communication components. Network information may include SNMP (Simple Network Management Protocol), Telemetry, Reporting, etc. Client 216 may receive and/or access data through Database 220, which receives updates via Database API 218. Client 216 may also communicate with a Local Admin Server 222. In this example, Local Administrator Server 222 may include a Local Kandy Admin Server that provides WebRTC to SIP services. WebRTC represents Web Real-Time Communication that provides web browsers and mobile applications with real-time communication (RTC) via APIs. Session Initial Protocol (SIP) represents a signaling protocol used for real-time sessions including voice, video, etc. Local Administrator Server 222 may communicate with Session Broker Controller 224 to various regions represented by North America Private Branch Exchange (PBX) 226, Europe, Middle East and Africa (EMEA) PBX 232 and Asia-Pacific (APAC) PBX 238. PBX represents a private telephone network used within a client, company or organization. Users may communicate internally within the client, company or organization as well as externally. As shown in FIG. 2, North America PBX 226 may communicate to Internet Service Provider (ISP) and/or phone/cellular service provider, represented by ISP/Carrier 228 and Public Safety Answering Point (PSAP) 230. PSAP may represent a call center that answers calls to an emergency number. EMEA PBX 232 may communicate to ISP/Carrier 234 and PSAP 236. APAC PBX 238 may communicate to ISP/Carrier 240 and PSAP 242. Other regions may be supported, in accordance with the various embodiments of the present invention.

An embodiment of the present invention may provide various end user services. An embodiment of the present invention may analyze metrics and other data. This data may be used to provide user forecasts and predictions. An embodiment of the present invention may also provide full API integration with various services, applications and/or other systems.
